Kua tāruatia ki te papatopenga
2x-\left(x+1\right)=6
Whakareatia ngā taha e rua o te whārite ki te 2.
2x-x-1=6
Hei kimi i te tauaro o x+1, kimihia te tauaro o ia taurangi.
x-1=6
Pahekotia te 2x me -x, ka x.
x=6+1
Me tāpiri te 1 ki ngā taha e rua.
x=7
Tāpirihia te 6 ki te 1, ka 7.
Ngā Tauira
whārite tapawhā
{ x } ^ { 2 } - 4 x - 5 = 0
Āhuahanga
4 \sin \theta \cos \theta = 2 \sin \theta
